It's a modest addition compared with the airline's recent international route schedule in April, which for Atlanta only included routes to Amsterdam and Mexico City, as well as to San Juan, Puerto Rico.
Delta is still cutting 85% of its flights in May compared with last year, including domestic and international flights.
The volume of airline travelers has inched up slightly in recent days, with the number of people passing through airport security checkpoints increasing to 154,695 across the country on Thursday, according to the Transportation Security Administration.
That’s down nearly 94% from the roughly 2.5 million passengers on the same day a year ago. But Thursday’s count was up from 87,534 people processed through airport checkpoints nationally on one day in mid-April.
Delta said its flight schedule "remains subject to change due to the evolving nature of COVID-19." The dates for flights starting up again will vary based on when travel restrictions are lifted and other factors.
The airline already pulled back on plans to resume flights from Atlanta to Buenos Aires, Argentina; Cancun, Mexico; Guatemala City; Liberia, Costa Rica; Nassau, Bahamas; Providenciales, Turks and Caicos; Quito, Ecuador; Santiago, Chile; and Sao Paulo, Brazil. Delta has removed those routes from its May flight schedule.
On May 8, Delta also halted plans to resume flights to Lima, Peru and San Jose, Costa Rica this month.
